An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.
The formula for the area of a triangle is A=1/2*b*h
A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3
Hope this helps
Step-by-step explanation:
the answer is in the above image
Answer:
P(A and B) = 0.1 = 10%
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question, we have that:

What is P(A and B)?


P(A and B) = 0.1 = 10%
I think it may be 5+3 and carry the one up top to get the sum of 56.
